Pune

I am assuming you want to go for a .BA degree in Hospitality Management form IIHM Pune. You will have to sit for the online entrance exam E-CHAT (Combined Hospitality Aptitude Test). Once you clear that there would be a group discussion and personal interview after which you'll get admited into the college.

Hello Abhishek,
Initially, you need to upload all essential documents like birth certificate, caste certificate( if applying through minority quota), mark sheets of 10th,12th and entrance exams.
But the final document verification needs to be done physically.
So atleast for a day you need to come down to city

D.Y. Patil, Symbiosis, Pune University and Singhad are some of the good institutes you can look for.

Hello Lokesh,
Admission in MIT, Pune is done via JEE Mains and MHCET. JEE Mains cut-off tend to be around 140-150 and in MHCET, it is around 120 -130. So as per your rank, your chances for admission via JEE is negligible, but MIT, Pune have management quota seats also so you may look forward for that too.
All the best!
